After going over a railroad track, at 15mph, several warning sensors appeared. Including brakes, power steering and several more flashed quickly. Power steering failed and I could not turn my wheel. It told me to not drive and see a dealer. Luckily I was in traffic and it was moving slow. I was able to turn my car off and back on and all the senor systems cleared. I took my car to the dealer, which it is at now, and they cant find a problem outside of wheel sensor going off in history. I dont feel safe with this car.

The vehicle came to a complete stop while attempting to enter the Highway. As I accelerated to gain speed, and the vehicle halted down to stop, all sensor warning systems started to light up on the dashboard: Adaptive Cruise Control, Automatic Emergency braking, Lane Departure Warning, Parking Collision Warning, Lane Keeping Assistance -- all sensors flashing simultaneously. As our vehicle stopped, the vehicles around us in the Highway had to abruptly stopped as well, causing a serious hazard, not only to myself and my family, but also the potential for a serious injury to other as well. This incident happened to us twice, and my passenger was able to record a video of the dashboard, as all the sensors were flashing and the vehicle switch to neutral on its own coming to a stop. We explained to the Honda dealership service department and after the second time, they kept the vehicle for service and it has been over (30) days since we had any update. The vehicle has been inspected by the dealership, and it is still there as parts are in back order, but there are not sure of what the real problem is. There were no previous warnings of this problem, the vehicle is a 2024 Honda Pilot Elite with 30,174 miles, and still under dealer warranty. This is the 3rd Honda Pilot I ever owned and never experienced anything like this before. My biggest concern is that if they do not fix this vehicle properly or if it is defective, my life and my family's will be in danger every time we drive it, as we do not know when it will decide to stop while driving.
The second-row seat belt sensor chimes persistently whenever the seat is occupied although the seat belt is buckled properly. Currently the only seat belt affected is the one directly behind the front passenger seat.
The second row passenger side seat belt warning sensor repeatedly pings even when the seat belt is connected anytime the passenger shifts in his or her position. It's as if the seat belt is not connected but it is. Not only is this annoying but it also means the driver is uncertain as to whether the seat belt is plugged in pro…

The second row passenger side seat belt warning sensor repeatedly pings even when the seat belt is connected anytime the passenger shifts in his or her position. It's as if the seat belt is not connected but it is. Not only is this annoying but it also means the driver is uncertain as to whether the seat belt is plugged in properly and has to manually check each time. Safety is therefore a concern. This happens whenever the vehicle is in operation and someone is using the second row passenger side seat belt. No other seats are affected. There has been no inspection of the problem but I plan to take the vehicle to a Honda dealer. My research online suggests this is an problem consistent with NHTSA investigation PE25017

Seatbelt warning system INCORRECTLY indicates with persistant and distracting chime and lights, that middle row right seatbelt is unbuckled, when it is in fact buckled. This has happened over 25 times over a 6 week period. It becomes a significant distraction to the driver, and forces the driver to ignore the seatbelt warnings all together, because while it is happening, it happens every 2-3 seconds continuously. Child passengers could very well be unbuckled ( Dangerous) and the driver wouldnt know it, due to the defective system. It is also extremely difficult to concentrate on safely driving while the chime is continuously going off. I urge the NHTSA to instruct HONDA to issue a safety recall and fix this dangerous issue.
The back seat seat belt warning malfunctions when someone is sitting in the back seat, causing the alarm to sound as if the passenger is not buckled in. The red seat belt notification also indicates that someone in that seat is unbuckled, which is incorrect. The seat belt is fastened the entire time. The notification alerts mid-…

The back seat seat belt warning malfunctions when someone is sitting in the back seat, causing the alarm to sound as if the passenger is not buckled in. The red seat belt notification also indicates that someone in that seat is unbuckled, which is incorrect. The seat belt is fastened the entire time. The notification alerts mid- trip while driving. This is extremely dangerous as a driver I thought our child unbuckled her seat belt while driving. This problem has been occurring for over 2 months. The problem has been inspected by a Honda dealership and diagnosed-Honda Technical Service Bulletin (TSB) A26-027 for certain 2023-2025 Honda Pilot vehicles. The bulletin addresses a condition where the vehicle incorrectly indicates that the second-row right passenger seat belt is unfastened, even when it is buckled.
In an accident where car collided with a concrete barrier on the highway at high speed, front drivers side, airbags did not deploy. Vehicle is available as of now, problem has not been reproduced, insurance representatives totaled the car but did not check the airbags, no warning lights or symptoms prior.
The right rear seatbelt keep’s going into alarm over and over like someone is unplugging it and plugging back in. The alarm is persistent no matter who sits in the seat. It flashes on the dashboard and the audible alarm sounds most if not the whole car ride every day.

2PE25017 · Inaccurate Rear Passenger Seat Belt Warning Status
Opened Oct 28, 2025 · No close date supplied
Status: open (inferred from source dates) · Seat Belts; Seat Belts:rear/other; Seat Belts:status Indicator Switch
The Office of Defects Investigation (ODI) has received 6 complaints, and multiple Early Warning Reporting (EWR) field reports alleging inaccurate rear seat belt warning status. These allegations concern both false positive and false negative statuses in model year (MY) 2023-2024 Honda Pilot vehicles manufactured by American Honda Motor Co. (Honda). The complaints state that the rear passenger seat belt warning system is displaying inaccurate information to the driver for both second and third row seating positions. This can lead to the driver dismissing warnings regarding rear seat belt status. The inaccurate information can also cause the driver to believe rear occupants are buckled when they are not. This reliance on false information presents concerns for the safety of children and child seats located in the rear rows, especially in the third row where the buckled status is more difficult for the driver to visually confirm. ODI is opening this Preliminary Evaluation (PE) to determine the scope and severity of the potential problem and to fully assess the potential safety-related issues. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data.
